5/16-24 x 1/4 18-8 Stainless Steel Low Head Socket Cap Screw is useful where the fastener head must remain lower than a standard socket head while retaining internal-hex drive access.

The 18-8 stainless steel material is commonly chosen for general corrosion resistance, clean appearance, and routine moisture exposure in common industrial environments.

The low head geometry gives this 5/16-24 x 1/4 fastener a reduced profile for conveyor systems and packaging equipment, where lower head projection can reduce snag points while still providing socket-drive access for maintenance. It may also be specified for compact equipment housings and panel assemblies, where internal wrenching keeps the drive feature inside the head when external wrench clearance is limited.

Use the verified dimensions below to compare nominal body diameter, head diameter, head height, hex socket size, and key engagement against the available space in the assembly.

Cold Headers serves machine builders, repair operations, and industrial distributors that need exact-size socket screws without exaggerated inventory claims.
